本文主要向大家介紹了Linux運維知識之Linux查殺stopped進程，通過具體的內容向大家展現，希望對大家學習Linux運維知識有所幫助。

在Linux系統下面，top命令可以查看查看stopped進程。但是不能查看stopped進程的詳細信息。那么如何查看stopped?進程，并且殺掉這些stopped進程呢？

ps?-e?j?|?grep?T

stopped進程的STAT狀態為T，一般而言,進程有下面這些狀態碼:

D????uninterruptible?sleep?(usually?IO)

I????Idle?kernel?thread

R????running?or?runnable?(on?run?queue)

S????interruptible?sleep?(waiting?for?an?event?to?complete)

T????stopped?by?job?control?signal

t????stopped?by?debugger?during?the?tracing

W????paging?(not?valid?since?the?2.6.xx?kernel)

X????dead?(should?never?be?seen)

Z????defunct?("zombie")?process,?terminated?but?not?reaped?by

its?parent

for?BSD?formats?and?when?the?stat?keyword?is?used,?additional

rs?may?be?displayed:

N????low-priority?(nice?to?other?users)

L????has?pages?locked?into?memory?(for?real-time?and?custom

IO)

s????is?a?session?leader

l????is?multi-threaded?(using?CLONE_THREAD,?like?NPTL

pthreads?do)

+????is?in?the?foreground?process?group

一般較常見的是5種狀態碼:

D?不可中斷?uninterruptible?sleep?(usually?IO)

R?運行?runnable?(on?run?queue)

S?中斷?sleeping

T?停止?traced?or?stopped

Z?僵死?a?defunct?(”zombie”)?process

所以，可以用下面命令ps?-A?-ostat,ppid,pid,cmd?|?grep?-e?‘^[T]’?查看stopped的進程信息。如下所示：

#??ps?-A?-ostat,ppid,pid,cmd?|?grep?-e?'^[T]'

T?????6777??8635?more?alert_pps.log

T?????6777??9654?tail?-60f?alert_pps.log

T?????6777?10724?top

#?kill?-9?8635

#??ps?-A?-ostat,ppid,pid,cmd?|?grep?-e?'^[T]'

T?????6777??9654?tail?-60f?alert_pps.log

T?????6777?10724?top

#?kill?-9?9654

#?kill?-9?10724
